Reddit reviews Goya Black Beans - Frijoles Negros 15.5 Oz Pack of 6

Ok, screw it. Let's do this.

• 1 15-pound bag of long-grain white rice. This has about 25,000 calories, per USDA data (google white rice nutrition facts) and costs $20.47 on Amazon
  
  
• 2 6-can packs of black beans provide 4,214 additional calories (439 grams per can 12 cans = 5,268 grams / 125 grams per serving = 42.14 servings 100 calories per serving = 4,214 calories). This costs us another $30.58 on Amazon
  
  At this point we probably need some more protein (the beans have a good amount of this) and fats to balance our diet, plus some veggies and other fresh stuff.
  
  
• 4 cans of Keystone chicken. This is minimally processed, and it's about the cheapest I could find. This gives us another 1,761 calories of much-needed protein, but comes at the relatively high cost of $28.32 on Amazon
  
  
• 1 two-pack of Jif creamy peanut butter brings us an additional 16,150 calories (yay, fats) at a reasonable price of $19.99 on Amazon
  
  Right now we're at 47,125 calories for the month, about 13,000 short of our 60,000-calorie-a-month requirement. We've already spent $99.36. We've tried as hard as hell to save money, our diet is technically balanced (though weighted heavily toward cheaper carbs) but is incredibly boring. I'd wager most people would like a little more variety than this. Perhaps you could throw in some cheap oats for breakfast and some cheap fruit and veggies to fill in the blanks. I still don't see how you're getting 60k calories in a balanced diet on just $110 a month.
